Touchless digital tachometer: new analog lover best friend?

How do you precisely measure the platter speed of your vintage turntable?

You do not care? Fine...

... but if you're wondering, from time to time, if your 50 years old turntable is still clever at it... well, for 25 bucks you can know it!

Try this... or any other digital gizmo with the vinyl spinning range - say 33 to 78 r.p.m. and a 0,1 r.p.m. resolution.

OK... you owe a beer to yours truly:-)))
